BRUSH MOTOR CARBON BRUSH CHECK AND REPLACEMENT [MICROMATIC M17B] (for machines
before 2007/05)
Remove the brush/pad-holder deck (see the procedure in the relevant paragraph).
At the workbench, remove dust and dirt from the outside of the motor, then disengage and remove the clamp (A).

Check if the four carbon brushes are worn out. Replace the carbon brushes when: the contact with the motor armature is
insufficient, the carbon brushes are worn, the carbon brush contact surface is not integral, the thrust spring is broken, etc.
If necessary, remove the nuts (D) and disengage the lead-in wires (E), then remove the carbon brushes.
Replace the carbon brushes as an assembly.
Assemble in the reverse order of disassembly, and note these items:
When connecting the terminals (E), take care of their insulation from the surrounding parts of the frame.
